Preliminary design of the HEBT of IFMIF DONES

IFMIF-DONES (International Fusion Materials Irradiation Facility–DEMO Oriented Neutron Source) is currentlybeing developed in the frame of the EUROfusion Early Neutron Source work package (WPENS) and will be aninstallation for fusion material testing, that will generate aflux of neutrons of 1018m−2s−1with a broad peak at14 MeV by Li(d,xn) nuclear reactions thanks to a 40 MeV deuteron beam colliding on a liquid Liflow.The accelerator system is in charge of providing such high energy deuterons in order to produce the expectedneutronflux. The High Energy Beam Transport line (HEBT) is the last subsystem of the accelerator and its mainfunctions are to guide the deuteron beam towards the Lithium target and to shape it by the use of magneticelements to the reference beam footprint at the Lithium Target.The present work summarizes the current status of the HEBT design, including beam dynamics, vacuum,radioprotection, diagnostics and remote handling studies performed, along with the layout and integration of theline.
This work has been carried out within the framework of the EUROfusion Consortium and has received funding from the Euratom research and training programme 2014–2018 and 2019–2020 under grant agreement No 633053. The work done by IREC has been supported by the CERCA Programme from Generalitat de Catalunya (Government of Catalonia).
